  • Neutrino mixings and leptonic CP violation from CKM matrix and Majorana phases 
    Agarwalla S.K.; Parida M.K.; Mohapatra R.N.; Rajasekaran G. (2007)
    The high scale mixing unification hypothesis recently proposed by three of us (R.N.M., M.K.P. and G.R.) states that if at the seesaw scale the quark and lepton mixing matrices are equal, then for quasidegenerate neutrinos ...

    Rajasekaran G. (Indian Academy of Sciences, Bangalore, 2019)
    Murray Gell-Mann, who passed away at the age of 90 years was a giant of modern particle physics. His most well-known contribution is the proposal that protons and neutrons are not indivisible but are made up of smaller ...

    The upcoming 50 kt magnetized iron calorimeter (ICAL) detector at the India-based Neutrino Observatory (INO) is designed to study the atmospheric neutrinos and antineutrinos separately over a wide range of energies and ...
  • TeV scale implications of non commutative space time in laboratory frame with polarized beams 
    Garg S.K.; Shreecharan T.; Das P.K.; Deshpande N.G.; Rajasekaran G. (Springer Verlag, 2011)
    We analyze e+e- → γγ, e -γ →γγ → e+e- processes within the Seiberg-Witten expanded noncommutative scenario using polarized beams. With unpolarized beams the leading order effects of non commutativity starts from second ...
  • Fermi and the theory of weak interactions 
    Rajasekaran G. (Indian Academy of Sciences, Bangalore, 2014)
    The history of weak interactions starting with Fermi's creation of the beta decay theory and culminating in its modern avatar in the form of the electroweak gauge theory is described. Discoveries of parity violation, ...
  • High scale mixing unification for Dirac neutrinos 
    Abbas G.; Gupta S.; Rajasekaran G.; Srivastava R. (American Physical Society, 2015)
    Starting with the high scale mixing unification hypothesis, we investigate the renormalization-group evolution of mixing parameters and masses for Dirac-type neutrinos. Following this hypothesis, the Pontecorvo-Maki-Naka ...
  • Predictions from high scale mixing unification hypothesis 
    Abbas G.; Gupta S.; Rajasekaran G.; Srivastava R. (American Physical Society, 2014)
    We investigate the renormalization group evolution of masses and mixing angles of Majorana neutrinos under the "high scale mixing unification" hypothesis. Assuming the unification of quark-lepton mixing angles at a high ...
  • Observing the dark scalar doublet and its impact on the standard-model Higgs boson at colliders 
    Cao Q.-H.; Ma E.; Rajasekaran G. (2007)
    If the standard model of particle interactions is extended to include a second scalar doublet [H+,(H0+iA0)/2], which is odd under an unbroken Z2 discrete symmetry, it may be called the dark scalar doublet, because its ...
  • Cobimaximal neutrino mixing from A4 and its possible deviation 
    Ma E.; Rajasekaran G. (Institute of Physics Publishing, 2017)
    It has recently been shown that the phenomenologically successful pattern of cobimaximal neutrino mixing (θ13 ≠ 0, θ23 = π/4, and δCP = ±π/2) may be achieved in the context of the non-Abelian discrete symmetry A4, if the ...
